2) The should consider that; 
a) The Amoeba dysenteriae has been shown to be the 
causative agent, from its constant presence in the stools and in the 
anatomical lesions and from the inoculation experiments of Kartulis. 
b) Clinically the disease is characterized by the presence of 
amoebae in the stools, which in addition present physical characters 
different from those seen in the stools of other forms of dysentery ; 
by a variable onset, course and duration, of which the special feat 
are periods of intermission alternating with exacerbations ; and by a 
marked tendeney to chronicity, with production of a greater or less 
degree of anaemia. 
c) Auatomically the disease is characterized by the production 
of ulcers in the colon which generally differ from those found in any 
other form of dysentery. The ulceration is produced by infiltration 
of the submucous tissue and necrosis of the overlying mucous mem- 
brane, the ulcer in consequenz having the undermined form. Fre- 
quently in addition to the ulcers there is an infiltration of the sub- 
mucosa without ulceration. In all of these lesions, unless compli- 
cated by the action of bacteria, there is absence of the products of 
purulent inflamation. 
3) Abscess of the liver, with or without involvement of the lung, 
is a frequent complication, much more so than in any other form of 
dysentery. The involvement of the lung may early follow the hepatic 
involvement and be detected by the occurrence of amoebae in the 
sputum before there is evidence of liver abscess. 
These abscesses differ in their anatomical features from those 
produced by other causes. The chief difference is found in the ab- 
sence of purulent inflamation, the abscess being caused by necrosis, 
softeniug an liquifaction of the tissue. In these liverabscesses the 
amoebae are not associated with any other organism. 
4) The disease is widely distributed, and is found in most coun- 
tries in Europe, in most patte of the United States and in the tro- 
pics everywhere. 
5) This is the form of dysentery which has been commonly 
called tropical dysentery.“
